Use |
|
Source of calories and essential fatty acids for patients requiring
parenteral nutrition of extended duration |
|

Contraindications |
|
Pathologic hyperlipidemia, lipoid nephrosis, known hypersensitivity to fat
emulsion and severe egg or legume (soybean) allergies, pancreatitis with
hyperlipemia |
|
|
Warnings/Precautions |
|
Use caution in patients with severe liver damage, pulmonary disease, anemia,
or blood coagulation disorder; use with caution in jaundiced, premature, and low
birth weight children |
|
|
Adverse
Reactions |
|
>10%: Local: Thrombophlebitis
1% to 10%: Endocrine & metabolic: Hyperlipemia
<1%: Cyanosis, flushing, chest pain, nausea, vomiting, diarrhea,
hepatomegaly, dyspnea, sepsis |
|
|
Overdosage/Toxicology |
|
Too rapid administration results in fluid or fat overloading to cause
dilution of serum electrolytes, overhydration, pulmonary edema, impaired
pulmonary diffusion capacity, metabolic acidosis
Treatment is supportive |
|
|
Stability |
|
May be stored at room temperature; do not store partly used bottles for later
use; do not use if emulsion appears to be oiling out |
|
|
Mechanism of
Action |
|
Essential for normal structure and function of cell
membranes |
|
|
Pharmacodynamics/Kinetics |
|
Metabolism: Undergoes lipolysis to free fatty acids, which are utilized by
reticuloendothelial cells
Half-life: 0.5-1 hour |
|
|
Usual Dosage |
|
Fat emulsion should not exceed 60% of the total daily calories
Infants and Children: Initial dose: 0.5-1 g/kg/day, increase by 0.5 g/kg/day
to a maximum of 3 g/kg/day depending on needs/nutritional goals; maximum rate of
infusion: 0.25 g/kg/hour (1.25 mL/kg/hour of 20% solution)
Adolescents and Adults: Initial dose: 1 g/kg/day, increase by 0.5-1 g/kg/day
to a maximum of 2.5 g/kg/day of 10% and 3 g/kg/day of 20% depending on
needs/nutritional goals; maximum rate of infusion: 0.25 g/kg/hour (1.25
mL/kg/hour of 20% solution); do not exceed 50 mL/hour (20%) or 100 mL/hour (10%)
Prevention of essential fatty acid deficiency (8% to 10% of total caloric
intake): 0.5-1 g/kg/24 hours
Children: 5-10 mL/kg/day at 0.1 mL/minute then up to 100 mL/hour
Adults: 500 mL (10%) twice weekly at rate of 1 mL/minute for 30 minutes, then
increase to 42 mL/hour (500 mL over 12 hours)
Note: At the onset of therapy, the patient should be observed for any
immediate allergic reactions such as dyspnea, cyanosis, and fever; slower
initial rates of infusion may be used for the first 10-15 minutes of the
infusion (eg, 0.1 mL/minute of 10% or 0.05 mL/minute of 20% solution)
